DTC Description

INFOID:0000000011277961

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (High or low resistance in the ECT sensor circuit)

• ECT sensor

FAIL-SAFE

Not applicable

DTC CONFIRMATION PROCEDURE

1.

INSPECTION START

Is it necessary to erase permanent DTC?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR

1. Turn ignition switch OFF.

2. Disconnect ECT sensor harness connector.

3. Remove ECT sensor. Refer to 

CO-23, "Exploded View"

.

4. Check resistance between ECT sensor terminals by heating

with hot water as shown in the figure.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Proceed to 

EC-215, "Diagnosis Procedure"

.

3.

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

• Before performing the following procedure, do not add fuel.

• Before performing the following procedure, check that fuel level is between 1/4 and 4/4.

• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 4.

DTC No.

ECT SENSOR
(Engine coolant temperature sensor 1 cir-
cuit range/performance)

The comparison result of signals transmitted to ECM from each tempera-
ture sensor (IAT sensor, ECT sensor, FTT sensor, and EOT sensor) shows 
that the voltage signal of the ECT sensor is higher/lower than that of other 
temperature sensors when the engine is started with its cold state.

PERFORM DTC CONFIRMATION PROCEDURE

1. Move the vehicle to a cool place.

NOTE:

Cool the vehicle in an environment of ambient air temperature between 

−10°C (14°F) and 35°C (95°F).

2. Turn ignition switch OFF and leave the vehicle for 12 hours.

CAUTION:

Never turn ignition switch ON during this procedure.

NOTE:

The vehicle must be cooled with the hood open.

3. Start engine and let it idle for 5 minutes or more.

CAUTION:

Never turn ignition switch OFF during idling.

4. Check 1st trip DTC.
Is 1st trip DTC detected?

EC-215, "Diagnosis Procedure"

.

NO

>> INSPECTION END

5.

CHECK INTERMITTENT INCIDENT

Refer to 

GI-44, "Intermittent Incident"

.
